Installation
5.1 General
The unit must be installed on a permanently even, smooth and
horizontal surface. The entire frame should be in direct contact
with the ground in order to ensure an adequate soundproof
seal, to prevent the water-bearing components from becoming
too cold and to protect the inside of the unit from small animals.
If this is not the case, additional insulation measures may be
necessary. To prevent small animals from entering the inside of
the unit, the connection hole in the base plate must be sealed,
for example. Furthermore, the heat pump should be set up so
that the air outlet direction of the fan is perpendicular to the
main wind direction to allow unrestricted defrosting of the
evaporator. The heat pump is fundamentally designed for in-
stallation on even ground. For different conditions (e.g.: fitting
on a platform or flat roof) or where there is a greater risk of the
heat pump tipping over (e.g. due to an exposed position or high
wind exposure), additional protection against tipping over must
be provided. The responsibility for the heat pump installation
lies with the specialist system construction company. During
the installation, local requirements such as building regulations,
the static load of the building, and wind exposure must be ac-
counted for.
It must be possible to carry out maintenance work without hin-
drance. This is ensured when observing the distances to solid
walls as shown in the figure.

NOTE
The heat pump is not intended for use above 2000 metres
(mean sea level).
CAUTION!
Do not restrict or block the area around the intake or the air
outlet area.
CAUTION!
Observe country-specific building regulations.
CAUTION!
Structural influences must be observed for installation close
to walls. No windows or doors should be present in the area
surrounding the air outlet of the fan.

CAUTION!
In cases of installation close to walls, there may be more
sediment in the intake and air outlet area due to the air flow.
The colder outside air outlet should discharge in such a way as
to not increase the heat losses in heated neighbouring rooms.
CAUTION!
Installation in a hollow or in an inner courtyard is not
permitted because cooled air collects at ground level and is
drawn in again by the heat pump during prolonged operation.
5.2 Condensate pipe
Condensate that forms during operation must be drained off
frost free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensate pipe must have a mini-
mum diameter of 50 mm and must be fed into a sewer in such
a way that it is safe from frost. Do not discharge the condensate
directly into clarifiers or cesspits. The aggressive vapours and a
condensate pipe laid in an area which is not frost-free can de-
stroy the evaporator.
